Bambu Lab chime maker / 01

Make your printer sing
the right part.

Drop in a MIDI—or extract a melody from an MP3—cut it to the perfect moment, and turn it into start or finish G-code.

♫
Demo sequence14 notes · 2 tracks · 120 BPM

MP3 melody extraction works best with humming, whistling, vocals, or a clean solo instrument. Dense full-song mixes produce an approximate lead melody.

BAMBU STUDIO / INSTALL GUIDE

Change the chime.
Keep the safety code.

The generated block belongs inside your printer preset. Do not replace the preset’s full start or end sequence—only its existing sound block.

!
Make a user-preset copy first

Factory machine G-code controls heating, homing, wiping, and other safety-critical behavior. Preserve everything outside the sound markers.

  1. 01

    Download the G-code block

    Choose Start chime in the editor above, then click Download .gcode or copy it to the clipboard.

    Save a personal copy

    Use Save As and give the preset a clear name such as “X1C 0.4 — custom chime.” This leaves the factory preset untouched.

    Find the existing sound block

    Search for M1006 S1. Select from the nearby “printer start sound” comment through M1006 W—and nothing else.

    Replace, save, and reselect

    Paste the generated block in the same position, save the user preset, and make sure that custom preset remains selected before slicing.

    Run a short test first

    Slice a tiny model and test at normal volume. If the printer reports invalid G-code, restore your copied preset and confirm that only the sound block changed.

    TEST

Bambu Studio labels can move slightly between releases. The key rule is stable: edit a saved user printer preset and replace only the existing M1006 sound block.
